An improved heat exchange construction for tube bundle heat exchange systems including shell (4) and tube (6) types (2), incorporating detached, essentially spherical flow interrupters (24, 26) arranged in an interconnected matrix configuration (22), and disposed within the tube bundle interstices (9, 11). Substantial improvements in heat exchange and exchanger tube life, is provided. The mechanically interconnected matrix configuration of the flow interrupters provides an economical and easily assembled means to improve heat transfer outside of individual tubes in a tube bundle configuration. Continuous tube support is also provided by tube/interrupter contact, thereby greatly decreasing fatigue failures encountered in presently used multiple tube, tube/shell heat exchanger configurations (2).

In a heat exchanger of the type utilizing a plurality of essentially longitudinal tubes carrying a first flowing fluid, and surrounded by a second flowing fluid for heat exchange therebetween, the improvement comprising; a longitudinal tube bundle having individual tube axis arranged in a predetermined pattern, said tubes having inner and outer surfaces; a plurality of interstitial fluid flow volumes defined by said tube outer surfaces, said volumes having first and second cross-sectional areas, and inlet and outlet ends; a flow interrupting matrix disposed in said interstitial flow volumes, said matrix comprising a rectangular grid-like configuration having flow interrupters and members interconnecting said interrupters disposed across said first and second areas respectively, thereby defining third and fourth flow areas for carrying interrupted flow in said flow volumes; means admitting fluid into and out of said inlet and outlet ends respectively; wherein interrupted fluid flow passing through said flow volumes enhances heat exchange between said first and second fluids.
